Graphics performance drop issue

[Lord Sephington]

Hey guys, im having some issues with my graphics.

 

I use an AMD A6 6400K with Radeon HD8470D (768mb) i have played games like BF4, need for speed hot pursuit and runescape. over the past 4-5 months things have been working well and i havent had any problems with playing those games.

 

But last night, i was playing need for speed and i was constantly getting error's forcing me to stop playing, the error was saying performance was below acceptable levels and it would kick me back to main menu. so i decided to switch to runescape, I loaded into the game but it came up like it was the 1st time i have played and wanted to optimize the graphical settings, i had most of these set to high, but when it auto calibrated and set everything to low with alot of options being switched off. 

 

I have the latest drivers for the GPU and i am at a loss as to what could be causing my problems, as my temps are no higher then 50c on both cores running at boost clock 4.1GHz

 

If anyone can give me any ideas as to what could be the problem (without saying to upgrade) i would be very grateful.

Potentially a corrupted driver. Have you tried reinstalling them?

Try rolling back to the latest drivers where you did not have these issues.
